Pearson's correlations between perceived attractiveness judged by opposite-sex raters and physical traits.
Confidence intervals are displayed in lower part (CI level = 95%). M = male photos; W = female photos; CZE = Czech Republic; EST = Estonia; SWE = Sweden; ROU = Romania; TUR = Turkey; PRT = Portugal; BRA = Brazil; IND = India; CMR = Cameroon; NAM = Namibia; Averag. = Averageness; FA = Fluctuating Asymmetry; SShD = Sexual Shape Dimorphism; EC = Eye color; Significance levels: * p < 0.05; ** p < 0.01.

Relationship between the Human Development Index (HDI) and Agreement with Czech Raters.
Using Kendall correlation, we identified a significant relationship for (a) male (τ = 0.67, n = 9, p = 0.01, 95% CI [0.25, 1]) but not (b) female faces (τ = 0.44, n = 9, p = 0.10, 95% CI [-0.10, 0.86]). On x-axis, agreement with Czech raters is expressed by values of bivariate correlations between Czech ratings and ratings of each target country.
